Abstract

The invention discloses a traditional Chinese medicine bulbus fritillariae cirrhosae DNA extraction reagent. The extraction reagent comprises a nuclear lysis solution, a CTAB buffer solution and a TEBuffer, wherein the nuclear lysis solution comprises Tris-HCl, EDTA, NaCl, PVP-40 and beta-mercaptoethanol, and is similar to the CTAB buffer solution in component. The DNA extraction reagent is suitable for extraction of traditional Chinese medicine bulbus fritillariae cirrhosae DNA, the removal rate of secondary metabolites is high, and the bulbus fritillariae cirrhosae DNA integrity is high. The invention further provides a traditional Chinese medicine bulbus fritillariae cirrhosae DNA extraction method. By adopting the extraction reagent, based on an existing CTAB method, improvement of anextraction reagent formula and optimization of extraction steps are carried out, so that high-purity and high-quality bulbus fritillariae cirrhosae total DNA can be obtained; and the extraction method is simple, easy to control and low in pollution.

Description

technical field [0001] The invention relates to the technical field of molecular biology, in particular to a DNA extraction reagent and an extraction method of a traditional Chinese medicine Fritillaria japonicus. Background technique [0002] At present, molecular biology technology has been widely used in the identification of Chinese herbal medicines, among which the extraction and purification of DNA is an important basis for the study of Chinese herbal medicines. Quickly and effectively extracting a large amount of high-quality DNA is the key to the implementation of molecular markers, gene An important prerequisite for library construction, gene isolation, genetic transformation and molecular identification. However, after most Chinese herbal medicines are processed, the DNA contained in them may be degraded to varying degrees, which is not conducive to maintaining the integrity of DNA; secondly, the secondary metabolites contained in Chinese herbal medicines are diffi...
